To aZZwLom t may concern.' p y l y Y k Be it known thatI, SAMUEL v-H.(uli1.soN, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented ertain new and useful Improvements in Hydroaeroplanes, of which the following is a specitication.

My invention relates to heavier than air ying machines, and has for its purpose to provide a device for carrying ,passengers through the air, which device may arise from or alight .on the ground or water, and which is strongly built and light in weight, and which is provided with a form and manner of wing construction which will require less propelling power than is at present used,` and which will remain in flight for a longer period of time when the propelling power is cut ott. These and other objects l accomplish with the device shown in 'the accompanying drawings and described in the specifications forming a part of this application and as pointed out in the appended claims, it being understood that slight changes in the manner and form of construction may be resorted to within the scope of the claims without departing from the spirit of the invention. p

lVith these objects in view my invention consists of the novel'construction and combination of parts which will be hereinafter described and claimed.

In the drawings Figure 1 is a plan view of the assembled device, much diminished from the other figures. Fig. 2 is a plan view of the body of the device with the covering removed from one side thereof and showing the covering and a. portion of the wing of the other side, parts cut awayv to show the interior mechanisn'i and structural formation.

My device consists of a body and tail'secti'on made in tubular form and retained in y that forni by longitudinally and laterally' placed truss braces, some of which are within and others without the structure and with laterally extended wings of special construction and form. Said wings are at tached to the braces inv said body and tail sections, and are so constructed as to sustain flight with less power and to carry more weight proportionate to said power than has previously been accomplished Also my device is so braced that the strainv of carrying weight and alighting on land or water will not injure the device. The body port-ion is in hollow tubular form braced within by a number of circular trusses A, and longitudinal braces 43 and 44. Each of said trusses'consists of tubes bent to form circular bands 1 and 2., concentrically spaced apart by radially disposed. braces 3. Said trusses A are spaced from each other and securely held in place by the longitudinal braces 43 and 44. Vithin each of said trusses A are also the are braces 5 and the tangential braces 6. The floor '7 of my device is supported by the are bracesl 5 and rests on the tangential braces G. In the tail y section' of my device'the tubular form is not so'nearly circular but is formed by two are shaped trusses 8 and the vertically placed Q ucsc/,eee

braces 9. Some of said longitudinal braces 43 extend longitudinally through the tail braces and to the rear of the device where they supportA the are shaped braces to which is pivotally secured the rear rudder plane 40 to be hereinafter explained.

That portion 'of the body of the structure below the floor'7, is covered with water proof material and forms a keel or water 10 tight compartment 11 in the underv part or body of the device, which is used as a buoyant element when the device is on the water. (See Figs. 5 and 8). The rudder wheels 12 are secured to the lower portion 15 of the body section of the device adjacent one of thc said truss braces A by means of a standard 13 which is rotatable within the bearing cylinder 21. Said cylinder is secured to the arc brace 5 and tangential braces 6 in said truss A. Said standard 13 is upwardly extended through the cylinder 21 and has a cross piece 15 secured thereto, forming lever arms to which the direction cable 51 of the device is secured. In alinement with and inclosing said wheels 12 and secured on said standard 13 which acts as a pivot therefor, are the rudders 16. Said rudders 16 are given the same longitudinal direction as the top rudder 17 Which is pivoted above the body portion of the device. Rudders 16 and 17 are used to give lateral direction to the device rwhen on the water or in the air. When on the water the rudders 1-6 control, and are used to turn the device to the right or left. On the said truss A at the rearend 0f the body portion of the device are fastened t-he rear wheels 18. Each of said wheels is journaled in a fork 19, on the upper portionof which is secured a piston 20, and the lower portion of each fork is braced by a stay 27.

- Each of said pistons is made to operate within an air cylinder 21 similar in form to the one on the front wheels,which is firmly held in place in the cross head 22 and normally in vertical position by the springs 23 and 24C. Said cylinders 21 with the pistons 2() provided therein, form air cushions for said wheels 18. The springs 23 and 24 allow the lower end of the forks 19, and said wheels,

to be moved from a vertical position, laterally on the pivotal connection of the cylinders to aid in alighting, with the rear end portion of my device the lower end striking theground first. Such construction is often desirable should the-device be skidding or bearing to the right or left when alighting.`

On the front of my device is secured the elevation rudder which consists of a plane 50 30 normally parallel with the general plane of the device. Said plane 30 has resilient 0I spring like strips 31 therein which are rigidly secured in a cross brace 32. On the free end of said strips 31 is provided the 55 flexing strip 33 which strip forms the front 34 and the respective cable disks 3G and 38.

The purpose being that when said lever '34 is moved on its fulcrum, the front edge of said plane 30 will be moved from its normal position, either up or down as said lever is moved. lVhen the pull of the said cables 57 is released from said lever 3-1, the resilient 8"0 strips 31 will return said plane 30 to its normal position. 'l'he rearrudder 40 is similarly constructed except as to size and form, it being made longer and wider and the rear edge preferably in curved form as shown at Ll1. The operating cables 57 and 58 leading to said planes 30 and 40 are secured to and wound on the same drum (lO but iu different directions in order that when said plane 30 is to flex downward the said plane -l-O is flexed upward and in the reverse directions respectively, and furnish the vertical control to the device, and thereby to move it from one altitude to another. The wings are alike on each side of the device and each wing consists of the upwardly curved plane ft2, to which is secured the upwardly curved auxiliary wing 41-6 with the resilient. members 4:7 firmly attached thereto. The said wings are detachably fastened to the body portion of my device by means of the eyes 48 engaging w1t-h the hooks 19 which are secured to the angle of incidence brace rods 1411, which are fastened on the outer side of a number of said truss braces A. There is one of said brace rods l-.l-Lt on ear-h side of the device and ofv length sufficient to reach from near the front, to near the rear end of the main body of the device; and each is inclined downward in the distance about the space between two of said braces 43. ln the outward tip of each wing is provided an aileron l5 by means of which the lateral stability of my device is maintained. Said ailerons coact to raise or lower the respective sides of the device7 and each is pivoted within a frame provided on the tip of the main plane.

The angle of incidence of the ailerons is changed and maintained by means of the cables 52 and 53. Each of said cables 52 ico and 53 are wound around a drum (31` which On one end of said-rock shaft 65 is provvided a depending weighted pendulum arm of an aeroplane somewhat similar was patented by me in July, 1910 and was numbered 965,771. pendulum arm 66 'and carried over pulleys to where the operator is seated, b, means of which the movement of the pen ulum may also be controlled by the operator. Said cable 52 has the ends thereof fastened to the ends of a lever 54 and the intermediate portion is wound several turns around and fastened on' said drum 61 by means of which cable the angle of incidence of the aileronon the right side of the device -is changed. Said cable 53 is also similarlywound on and secured to said-drum 61 and has its ends fastened to a like lever on the aileron at the left side of the device in order that the rotation of said drum 61 will change the angle of ineidence of both ailerons but in the reverse direction by which means-one wing of the device is raised and the other wing lowered, by the one movementof the drum. Each wing is firmly held in fixed tangential relation to the body of the device by the stay wires 55 and 56. Said wires 55 are fastened at their inner ends to the horizontal truss brace 25 which is fastened to the upwardly extended radial braces 3 and' their side braces 26. their inner ends to the truss braces A.

The cont-rol of my device consist-s of a hand wheel 7 0 secured on the end of a shaft 71 which is journaled in vertical standards or bearings 72, and another hand wheel 73 which is fastened on one end of a. drum 60, which drum and wheel are also carried .on said shaft 71. The said hand wheel 70 has a ratchet 75 which forms the hub 0f said wheel and which ratchet is engaged by a detent 76 slidably carried in a case 77 and pivoted to -al foot pedal 78. Said detent 76 is normally Aheld in engagement with said ratchet by means of' a spring 79. Outwa'rdly extended flanges 80 are provided on said drum69 .to form cable cases S1 and S2 on which the said cables 50 and 51 are respectively wound and fastened. Said drum 60 has outwardly extended flanges 83 to form cable cases 84 and 85, on which said cables 57 and 5S are respectively wound and fastened. 73 will move said cables 57 and 5S, and the rotation of said hand wheel 70 will move said cables 50 and 51. The hub of said hand wheel 73 is/formcd as a ratchet 86 which rotates with said wheel. The teeth of said 'ratchet 86 are/.engaged by a-detent S7 which is slidably carried in a case 88 that is fastened to one of said standards'72 and on the opposite side is fastened said case 77. .Sai-d detent 87 is pivoted at the lower end to an Cords 67 are fastened to said Saidwires 56 are fastened at,`

The rota-tion of said hand WheelA Vother foot pedal 89, which is pivoted adja- 'cent said pedal 78. Said detents 76 and 87 are to lock said hand wheels and 73 against unintentional rotation.

In the diagrammatic Fig. 17 the position and shape of the portions of each wing are shown more clearly than in the other figures. The main wing 42 has its edges in a plane as shown in Fig. 7, i'nmiediately` back of the frontedge, the wing curves upward and then downward to the general plane thereof, and to the rear edge of this portion of the wing is secured the auxiliary wing 46, which auxiliary wing is also curved upward above the general plane, and with the rear edge thereof preferably in a lateral curved line and to which lateral curved line edge a plurality of resilient members 47 are secured, each parallel with the body of the device and in transverse alinement with the front edge of the main wing and they, general plane. The purpose of the several wing sections and of their form and construction being, that when the device is formed through the air there will be a compression of air under the curved portion of the main wing, and the air in escaping to the rearward, will pass under the curved auxiliary wing 46 and strike the said resilient members 47. The` air in escaping from under the said members i7 will cause the resilient tips or the free end portions thereof to bend or curve upward and with a tendency to force the device ahead.

My purpose is to construct a wing similar to the wing of soaring birds-'and to supply, 'with the resilient tips 47 of the members 46, .the wing feathers on the rear side of the birds wingsand to thereby secure enough forward movement from the resiliency in said tips as acted upon by the escaping air to prevent a vertical fall and to alight safely should the propellers stop and the momen tum given the device by them be much diminished or entirely eut off'.

The power plant of my device consists of an engine 92 in the right and a similar engine 93 in thel left side of the device secured to the floor 7. Both connected b v a belt 101 to a lateral counter-shaft 102 in order that said counter-shaft 102 may be rotated by either or both of said engines. On each end of said counter-shaft 102 is provided a bevel gear 103, which meshes with bevel. gears 104C which are secured on the ends of the prol peller shafts 105. Said counter-shafts 102 'and propeller shafts 10j/"i areyjon/rnaled in vided with two loosepulleys 109, and a friction clutch 110 adjacent each of said pulleys,

in order that either'enginemay be thrown .ot which either or both propellers4 may be thrown out of or into motion.

L The levers to move the friction clutches 110 are shown at 112, those for the propeller` shafts are not shown.

0n each side of the device, and centrally located on the under Side ot each 'of the main wing sections, is pivoted a dependable loat 100; preferably circular in torni and made of two convex disks secured together at the 4rperipheries, the vupper of said disks havinga ycentral portion formed concave. Two tubes 94 are pivoted at one end to the under side of the main wing section andv their other ends are fastened together to form a V-shaped link brace which 1s pivoted to said float centrally within the concavity v:formed in' the upper side thereof. Said V- shaped link has cords 95 and 9G attached at the lower end and at opposite sides'thereof.

Said cord 95 is made to operate over a pulley 97 secured near the-outer end ot said main wing and over a pulley not shown, secured to one of said longitudinal braces 43. Said cord 96 is made to run over a pulley not shown secured to the same,

cords 9.5 and 9G fastened to form stays and maintain or hold said float in vertical position. Each of said floats'rests on the surface of the water and insures lateral sta-.

bility to the device. W'hen the device is to be operated, either on the water or in the air, the cord 95 is loosened from said tie and allowed to move over the pulleys 97 and 98 and the cord 9G is drawn inward over the pulley 99, and thereby the lioats are brought into the position shown in dotted lines in Fig. '1,- where lthey otter the least resistance and in that position they are held until needed to again rest upon the Water.

The control 'and operation of my device is as follows: To more on the water, the water proot keel ll will lioat the device, with the wheels and front lower rudders 1G submerged, motion being imparted to the propellers 90 by the engines 92 and 93, or either ot' them, said propellers will engage the surrounding air and the device will be forced ahead. lVishing to turn to the right or lett, for illustration say to the right, the free end ot the foot pedal 78 is pressed down, this disengages the detent 76 from the ratchet and leaves the hand wheel 70 free to rotate on its axis. By turning said hand wheel to the left and the said and the rudders 1G and 17 are turned l,to the right. A reverse turn of said hand wheel 7 0 will direct the device to the left, and releasing the foot-pedal 78 when the rudders are turned to the left' will allow the detent 7 G Ato engage the ratchet 75 and hold the rudders in that posit-ion and the device will run in a circle to the lett, With the rudders set parallel with the device, and wishing to arise the :tree end ot the other foot pedal 89 is depressed, this will disengage the detent 87 from the ratchet 86 and leave the hand wheel 73 free to be rotated on its axis. By turning the said wheel to the right the cables 57 andv 58 will be moved longitudinally and the front edge portion ot' plane 304 will be curved upward, and the rear edge portion of the plane "l0 will be curved downward, this will direct the device upward out of the water and into the air. To continue to rise, the pressure on the :toot pedal 89 may be removed, if desired. This will allow the detent 87 to engage the ratchet 86 and lock the hand wheel 73 which will hold the said planes 30 and 4:0 in their upward and downward curved form respectively. Vhen the desired altitude has been attained, the said foot pedal 89 is depressed to release the said hand wheel 73, when so released said wheel and its connections are tree to move and the resilient strips 31 in said planes 30 and 40 will bring the sa-id planes 30 and 40, which are the elevating rudders, to their normal and horizontal position, this will keep the device at that altitude. f It the air currents tilt the device from a lateral horizontal position, for illustration say that the right wing is raised and the left Wing is lowered, the pendulum 6G will be moved to the lett and the segment gear 64 turned to the left. Said movements ot the pendulum and segmentgearwill rotate said drum (il and move the cables 52.

and longitudinally, and this movement will have pulled the front of the aileron 45 cables 50 and 51 are moved longitudinally right' wing and raise the left wing and bring the device back to the lateral horizontal position. It at any time the said pendulum should from any cause have a tendency to oscillate, this may be prevented by means ot said cords G7.' Should it be necessary or desired at any time to hold the device. with one wing raised and the other lowered as in banking on a turn,\say to the lett, the said cord G7 on the right is pulled, thus drawing the pendulum to the right. Holding vit in that position will hold the front of the aileron in the right wing up and the 'front of the aileron in the left wing down. It the said cord G7 is released the pendulum will immediately swing beyond the vertical and reverse position of the ailerons and bring the device to a lateral horizontal position. The planes, wings and body of the device are each covered with wires crossed to form a mesh orscreeu7 which is covered with thin silk; cloth or strong paper, and cemented to gether with shellac, rubber or other water 10 proof cement. Having thus described my invention I desire to secure by Letters Patent and claim :-y
